Do they have a better execute than lighting? It seems like this execute has been over used.

Even though I will not ignore the problems of China high speed railway, I am still a firm supporter of its building. To me, building for the future and the problems of building can be independent issues.

I don't think we need to build this fast. I believe China only need two major connection routs for the current stage - one is Beijing-Shanghai-Guangzhou-HongKong, and the other one is Shanghai-Nanjing-ChangSha-Chengdu-ChongQing.

I believe they should just build a few major connecting routes for now. To allow the opportunities to mature the technologies, mechanical productions, railway construction, operations and management, and market demands.

For examples, Shanghai only had two subway lines for years. One was built under Germany guidance (I believe my memory is correct) and the other one was built by its own (it had quite a few problems when it was first put into operations). When the time came, it just expanded the subway lines to more than 10 just in 3 years.

Therefore, China shouldn't expand its high speed railway networks to the current size and at the current speed. Of course, 為政績搏上位 should be the major motive.

Yes, that is why I said it should not be built to the size as it is now.

My concern is not whether this accident is a high speed railway or not.

Construction and hardware installation is relatively easy to proceed. The most difficult part is the operation and management. It cannot be rushed and experience must take time to be accumulated (no exception with that).  

Just like building a aircraft carrier fleet. The cost of personnel training could be as high as the cost of building the ships. More importantly, it takes times.

Managing two major routes is easy, but operating a sizable network is a different story.

A Japanese that I know is specialized in the research of the optimization of "traffic light control system " of city traffic. The same research can also be applied to the coordination of railway networks. The topic sounds simple but it is, in fact, a very difficult challenge to tackle.

I believe there are more government officers will be and shall be "人頭落地".
